A car has a full tank of gas, holding

15 gallons

. It drives

300 miles

, and then stops for gas. After

10 gallons

of gas are added, the tank is full again. What is the gas mileage of the car?

The mileage of the car is 30 miles per gallon

Step-by-step explanation:

Here, we are interested in calculating the gas mileage of the car.

The gas mileage refers to the number of kilometers the car can travel on a particular amount of fuel.

The full capacity of the car tank is 15 gallon

Now after traveling 300 miles, it stops for gas and 10 gallons of fuel are added to make the car full again.

What this means is that the car used up a total of 10 gallons of fuel for the 300 miles

Thus, the gas mileage of the car is that it used 10 gallons to travel a total of 300 miles

Expressing this as a ratio, we have 300 miles/10 gallons = 30 miles / gallon

This means that on a gallon of fuel, the car can travel 30 miles
